1. The Global Water Gap
By Borges and Kusena

2. Fig 2.36 pg 386 shows information on the average use of water per day between 1998&2008.
Looks at selected LEDC’s and MEDC’s.
They are separated by country according to average water supply per individual per day.
The difference is the ‘water gap’
Can be split into 2 sections LEDC’s and MEDC’s.
In ascending order of litres per day

3. LEDC’s
General trend shows that most LEDC’s have the lowest average use per person per day(0-50)
Some as low as 10L per day e.g. Mozambique
Reasons:
Poverty
Pollution
Political conflict
Rapid population growth

4. Some exceptions.... India- monsoon rain storage in reservoirs and dams
Brazil- Most towns are coastal, so they benefit from fresh water flowing to the sea from he rain forest affected by little pollution.

5. However....
Level of development does not affect the amount of water per person per day e.g. UK(140l)compared to Brazil(180l)

6. MEDC’s
The US (570l) and Australia (490l)have the highest average use of water per person.
Australia-
Low population
Good Economy
Not necessarily good water supply.
High individual income
therefore have a low strain on resources
They can afford sewage treatment, purification of sea water etc
Don't have a good supply but can manage it well( most of central Australia is desert)
Individuals can afford to pay extra for running water at home or bottled water

7. Other reasons Physical scarcity according to location.
Climate (good in equatorial e.g. Brazil)
Altitude
Rivers & lakes
Ground water supply
Rainy season
